dots & diamonds

so I've just began an idea of a simple hairline serif typeface.
I am very early in the process of putting it together but I've come across a small dilemma: should I dot my /i/s and /j/s or do diamonds add a little class or sophistication? is there certain protocol for this or is entirely based on opinion, etc.
I've attached the letters for reference.

Your tittles are very high, and need to be optically centered above the letters, not mathematically. I also don't think you should include both variants, but that's just me. They're such a big part of the design.

Fair point, Frode. If you want to licence the font then that might help create a personality, but then it might also be a selling point to have some alternatives! Changing the tittle does produce an unusually large change in overall appearance (dots always seem friendlier than blocks, for example), so it is worth bearing in mind.

Isn't there also some notion that diamond tittles, punctuation, etc. denote a kind of calligraphic thrust? That's how I always interpreted something like Kabel, that gets more brush stroke–like (or woodcut-like, maybe) as it moves toward heavier weights. This goes even more for Fedra, but then it's fairly modulated.
